Without the inverter on, we can't use the receptacles below the sink, bathroom, main t.v or the outside receptacles. Once the inverter comes on, we can run these for a period of time and then it shuts down.

When the inverter is on, the battery indicator reads 13.5. The bathroom receptacle does not pop nor do any of the breakers or fuses.

I have checked the batteries, looked at the wiring trying to diagnose the problem. Is this normal?

Are you plugged into shore power? On shore power, the 110 volts passes through the inverter to the items you described whether the inverter is on or off.

If not on shore power then the inverter needs to be on to provide 110 volts (from the batteries) to those items. When the inverter is providing the 110 volts from the battery (not on shore power) the inverter will shut down if the battery voltage gets too low or if the output load is above its limits.

What RV year and inverter model do you have, maybe my 2010 RV with Xantrex XM 1800 operates different from yours.

On mine, when plugged in to 110, the 110 passes through to the items you described with the inverter on or off at the control panel on the wall. Also, the battery switch has no effect on the inverter passing through the 110.Bob

I too have had this problem for awhile and decided to diagnose it. I found that even though I was plugged in, the Xantex 1800 would not allow 'pass though' capabilities of 120v to the outlets.

I then put in a call to Kermit to see if he had a magic bullet for this. It turns out Xantrex sent out a few bad apples and the unit will need to be changed out. Didn't you pick your Cruiser up right before we did in late October? If so, probably THAT batch of inverters.

Please call Kermit and see what he would suggest. He is going to exchange mine when I am up in Elkhart in 2 weeks, maybe he can ship one to you so an RV electrican can install? It's not a difficult task, but I would suggest disconnecting the 12v positive and NOT have the Cruiser plugged in.

George, did you ever get your inverter problem resolved? I am having some electric problem with my 2010 PC and I am suspecting it is inverter related. Guess I should give Kermit a call. I hope he is as forthcoming as everybody say he is. Thanks
